RAZOR HEAD GUARD Filed Sept. 23, 1963 J7 20 22 {unw- {1 16 2o u n l WINlgNTOR PATENT ACEN T United States Patent 3,177,582 RAZOR HEAD GUARDCarl Curtis, RR. 3, Cobourg, Ontario, Canada Filed Sept. 23, 1963, Ser.No. 310,645 1 Claim. (Cl. 30-90) This invention relates to head guardsfor safety razors. Although it is recognized as being quite desirable toprovide a head guard for a safety razor in order to protect or shieldthe blade edges, such guards are not in widespread use for variousreasons. It is of course important that the contour of the guard be suchthat no contact with the blade edges occur. It is furthermore importantthat the guard be subject to easy and convenient applica a minorlongitudinal section depending from each side of the major section, andan intermediate longitudinal section joining each of the minor sectionswith the major sections. The intermediate section has a cross sectionsharply curved with respect to the arcuate contour of the major sectionand an inturned flange constituting each longitudinal terminal edgeportion of the strip. A longitudinally extending rib projects from eachof the intermediate sections, these ribs constituting a handle for theguard and being swingable towards each other to impart bending movementto the major section and to swing apart the minor sections and theflanges.

It is an object of this invention to provide a head guard for safetyrazors which is of simple, inexpensive manufacture, which acts as aneffective shield for the blade edges without risk of damage thereto,which is adapted to securely maintain its position on the razor head,and which may be conveniently and quickly applied to and removed fromthe razor head.

The invention will be described with reference to the accompanyingdrawing, in which FIGURE 1 is an end elevation of a razor head with anassociated guard in accordance with the invention,

FIGURE 2 is an end elevation similar to FIGURE 1 but showing the guardin substantially locked position on the razor head, and

FIGURE 3 is a perspective view of the razor head and guard assembly.

, Referring to the drawing, 10 is a conventional safety razor headhaving a blade seat member 11, a blade 12 and a movable bladepositioning and retaining frame 13. Frame 13 has a blade positioning rib14, and a pair of pivotally mounted cover plates 15 each with anactuating lug 16. The blade seat member 11 has depending blade guardlips 17 beneath which are located the lugs 16 for engagement with thelips to effect opening movement of the frame, all in the usual manner.

Thehead guard in accordance with the invention is indicated at 18 andcomprises a strip of thin, spring sheet material of form-retainingrigidity such as spring metal or plastic composition. In cross section,the strip has a major longitudinal section 19 of arcuate contour, aminor longitudinal section 20 depending from each side of section 19 andjoined thereto by a relatively sharply curved intermediate section 21.Each longitudinal edge portion of the strip comprises a substantiallyflat inturned flange 22.

Projecting outwardly from each intermediate section 21 is alongitudinally extending rib 23 constituting a handle member.

In use, the sections 20 with flanges 22 are sprung apart by grasping theribs 23 and pressing them towards each other. The guard is then placedover the razor head as shown in FIGURE 1. It will be observed that, inthis condition of the razor head, the blade set is in partially elevatedposition, the edges of lips 17 being slightly above lugs 16. Followingthis procedure, the handle of the razor is further actuated to fullyraise blade seat 11. Since the rib 14 is in engagement with the innersurface of section 19, this elevating movement will cause the edges oflips 17 to engage the inner surfaces of flanges 22. Thus, the guard 18is securely clamped in position on the razor head.

It will, of course, be realized that the position of the variouselements of the razor head, when the guard'is is clamped thereon asdescribed, is that recommended when the razor is not in shaving use,i.e., the blade 12 is in freely seated and unflexed condition.

It will also be observed that, in both the unclamped and clampedpositions of the guard, theinner surfaces of the depending sections 20are spaced from the blade edges to avoid damage thereto.

I claim:

A safety razor head guard comprising a strip of flexible spring sheetmaterial having a major longitudinal section of arcuate contour in crosssection, a minor longitudinal section depending from each side of saidmajor section, an intermediate longitudinal section joining each saidminor section with said major section, said intermediate section havinga cross section sharply curved with respect to said arcuate contour ofsaid major section, an inturned flange constituting each longitudinalterminal edge portion of said strip, and a longitudinally extending ribprojecting outwardly from each said intermediate section, said ribsconstituting a handle for said guard, and being swingable towards eachother to impart bending movement to said major section and to swingapart said minor sections and said flanges.
